Application filed February 23, '1853. (No nddl.)

To LZZ whom `tin/ty concern,.- 'Beitknownthat, JorLNRUssELL,`a citi` `z'en of the UnitedfStates,"residing a'tBerlin,j in the county of Somerset and "State of Pennsyll vania, have invented certainnew and' useful Improvements in` Grain-Separators", and I "dof declare the following to be` a full, clean and exact description of the invention, such as will enable others skilledin the art `to which lit "ap-Al motor. `Io this shaft is secured a pertains to make` and usefthe Same, being had tothe accompanying drawings,- and' to letters and figures of reference marked there-f` on, which form a partof this specification.

This invention 'relates to that of grainseparating machines` in which the"` grain l is cleaned by the action of induced air-currents.` The invention consists of a double ,f igrain-,sepa-u rater in which the parts are constructed and arranged as hereinafter described an'dclaimed, whereby the capacity ofthe machineis largely increased without involving a proportionatev increase in bulk. y

In the annexed drawings, Figure l represents a longitudinal sectional elevation of my iin-` proved grain-separator on the line y y of Fig. 2. Fig. 2 is atransverse vertical section on the line :v :o of Fig.: l. Fig. 3 is anend view, partly in section.` jFig. 4 is a transverse section 011 the line e z of Fig. l.

A represents the framework of the machine.

Bis a vertical shaft journaled in a step in the bridge-tree A. The shaft B has a pulley near its lower end, by `means of which it Vis driven by a belt or` chain from any suitable an, B'. that revolvesin the fan-case B2, which is pro# vided with the opening or mouth a., `as seen in Fig. 1.-

Gis the air-chamber, communicating with the fancase by means of `an opening,b, around the shaft. Above the air-chamber C, and journaled in suitable bearings, is a vertical shaft, c, provided with apulley and an eccentric, c', to which is secured a pitman, D, the other end of which pitman is fastened to the under side of the inclined shoe E. A belt passing from a pulley on the upper end of the shaft B to the pulley on the shaft c rotates the shaft c andoperatesthe pitman, thus vibratf, ing the shoe E. This `vibratory shoe is supported by the Springs d d, and is provided with a hopper and two screens, as shown in reference o. Fig. l. It alsohas a longitudinal partition,

e2, as shownin Fig. 2, for thepurpose of ef# fecting a more equal division of the quantity sides of the inclined spout H.

The grainis first fed into the machine through the hopper F, `from which it passes down the double-inclined plane F, through theports e e,

sidesof thelmachine, where` it is subjected to `upward currents of air induced toward the air-chamber by the revolutions ofthe fan B.

These drafts of air carry the dust, chaff, and

2 lighter particles `up over the" arches e e and down into the suction-spouts Gl G, whence the chaff passes through the openings f f into the I airfchamber C, and through the aperture b of the same to thefan, and is-allowed to'escape through the mouth a. The screenings and heavier particles pass out at the inclined bot- '.or valves g g, to prevent the valuable portions ofthe cleanings from entering the air-chamber. rlhe grain thus freed from dust and chaff next E, the upper screen carrying off the straw, corn-cobs, and larger foreign substances i by a spout or other means (not shown) to the side of the machine, while the grain falls through the upper to the lower screen, the sand and other smaller impurities passing through the lower screen, and being conveyed from the end of the same by a spout (not shown) to the side of the machine. The grain thus cleaned passes from the shoe/to the double-inclined spout H, which extends across the machine to the arched suction-spouts II on each side. The grain passes through the ports 7L h'into the spouts I I, as seen in Fig. 3, andis a second time freed from dust, 85e., by an upward current of air in-V duced toward the air-chamber by the revolutions of the fan.` The dust and chaff are carried openings k k, into the air-chamber, as seeniu allowed to waste into the open air at a, or be receivediin suitable receptacles, after which ofthe spouts (see Figs. 3 and 4) into hoppers t" i, which convey it to the suction-tubes J J,

`of grain delivered therefrom to the opposite` the grain passes out of the spouts I I bymeansv intothe conductorsor spouts G G on both i toms through the valvesf` f', as indicated in passes from the spouts G G tothe inclined shoe by thecurrent through the spouts I I, through Fig. 4, and by the opening b to the fan, and then IOO through which it escapes, and where it is subjected to a third and final upward draft of air created by the fan B', which carries up any remaining light impurities over the arches into the spouts J' J and into the air-chamber through the ports 7c' k', (see Fig. 4,) the screenings passing out through the valves Z' Z' at the ends of the inclined bottoms, as seen in Figs. 1 and 3. The drafts in the' spouts J' J' are regulated by means of the adjustable valves or delectors Z Z, having set-screws Z". The grain thus cleaned passes out at the Open ends of the spouts J J.

It will thus be seen that the grain while passing through the machine is subjected to the cleaning action of strong air-currents at three distinct points on each side of the double machine-atrst just before reaching the vibratory shoe, again immediately after passing the shoe, and finally after leaving the hoppers i' i' before escaping from the machine. rIhese aircurrents are all induced by the fan B', which draws the dust and chaff into the air-chamber, whence it is discharged through the Opening a, the air-currents thus induced being sufciently powerful to effect a thorough cleansing of the grain.

By arranging the vibratory shoeE to act in conjunction with a double incline, F', and a spout, H, diverging tO each side of the machine, and arranging the suction-spouts in the l manner described, so as to receive and discharge grain on both sides of the machine against the action of induced air-currents passing through said suction-spouts to the fan case,

I am enabled to largely increase the capacity of such machines without a proportionate increase in bulk or space. This machine is capable of effecting a thorough separation of all extraneous substances of less weight than that of the grain under treatment.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

y 1. In a grain-separator, the combination, with the vibratory shoe E and a single fan, B', of the hopper F, double-inclined plane F', double -inclined spout H, arched suctionspouts I I, and the arched suction and discharge spouts G' G' and J J', said suctionspouts communicating with the fan case through suitable Openings, whereby the grain is cleaned and discharged in divided streams A or portions, substantially ,as described.

2. In a grain-separator, the combination, with the vibratory shoe E, having a central partition and carrying suitable screens, of the double-inclined plane F and double-inclined spout H, substantially as described.

3. In a grain-separator, the combination of the vibratory shoe E, double-inclined spout H, arched suction-spouts G G', I I, and J J', spouts 'i t', and hoppers i' i', substantially as described.

In testimony whereof I afiixmy signature in presence of two Witnesses.
